The gas blowing device is composed of a gas inlet pipe, a gas collecting pipe and a gas exhaust pipe, the gas inlet pipe, the gas collecting pipe and the gas exhaust pipe are intersected at one position together to be communicated, a pipe opening of the gas inlet pipe is connected with the blowing nozzle, a pipe opening of the gas collecting pipe is connected with a gas connecting bag, and one-way gas outlet valves are arranged in the gas collecting pipe and the gas exhaust pipe respectively. According to the exhalation test gas collecting device, gas, firstly exhaled by a patient, in the bronchia and the oral cavity is exhausted, only lung gas exhaled in the last stage of exhalation is collected, and the accuracy of exhalation test detection results is guaranteed.
Description
Technical field
This utility model relates to medical instruments field, particularly a kind of breath test gas collector for detection of digestive system disease.
Background technology
For a long time, the digestive system disease such as gastritis, gastric ulcer, duodenal ulcer cause very large painful and puzzlement to patient always, at present in the time checking these Gastroenterology dept.s disease, often need by gastroscope, patient's stomach to be observed, with the clear and definite cause of disease or the ill order of severity, but because the method need stretch into patient's stomach along esophagus by gastroscope, can bring strong sense of discomfort and misery to patient.
For the deficiency of gastroscopic observation method, occur that in recent years a kind of breath test method detects digestive system disease, its principle is, another patient first takes through isotope-labeled capsule or pill (as C13, C14 capsule), C13, C14 in capsule can react on stomach and the antibacterial (helicobacter pylori) of curing the disease, and formation is labeled
13cO
2,
14cO
2, therefore, after the gas that patient is breathed out after taking medicine gathers, as found to contain above-mentioned marked carbon dioxide in gas, prove to have the antibacterial of curing the disease in patient's digestive system, be subject to infection.Obviously, this method only needs patient to take medicine and exhale, and compared with gastroscopic observation method, has advantages of convenient, fast, no pain.
But, the existing breath test method part that also comes with some shortcomings.Such as, patient is in the time exhaling, what first breathe out is the gas of oral cavity and throat, be only subsequently pulmonary gases required in breath test, therefore Storage Time in Gas Collecting Bag can only could be collected pulmonary gases collecting after all oral cavities and trunnion gas, cause the pulmonary gases content in collection bag few, affected the precision detecting.
Utility model content
For the problems referred to above, this utility model provides a kind of breath test gas collector, the trunnion that this device can first be breathed out patient and intraoral air scavenge, be only collected in the pulmonary gases that very end of exhalation is breathed out, and guaranteed the precision of breath test testing result.
To achieve these goals, a kind of breath test gas collector that this utility model provides, comprises blow gun, Storage Time in Gas Collecting Bag, also comprises a blowning installation; Described blowning installation is made up of air inlet pipe, discharge and exhaustor, and described air inlet pipe, discharge, exhaustor are intersected in a place and are communicated with; The described air inlet pipe mouth of pipe is connected with blow gun, and the described discharge mouth of pipe is connected with collection and confinement of gases bag, in described discharge and described exhaustor, is equipped with unidirectional air outlet valve.
Preferably, the described exhaustor mouth of pipe is connected with exhaust gas recovery bag.
Preferably, described air inlet pipe, discharge, exhaustor are T-shaped and are interconnected.
Preferably, described Storage Time in Gas Collecting Bag bag mouth inner side is provided with female thread, and is connected with the discharge mouth of pipe by an external screw thread body matching.
Preferably, described blow gun is silica gel blow gun.
Preferably, described silica gel blow gun is provided with groove.
The breath test gas collector that this utility model provides, between blow gun and Storage Time in Gas Collecting Bag, set up a blowning installation, this device is by air inlet pipe, discharge, three bodys of exhaustor are intersected in place connection and form, discharge is connected with collection bag, air inlet pipe is connected with blow gun, on discharge and exhaustor, be equipped with the unidirectional valve of giving vent to anger, in the time that patient blows, the unidirectional air outlet valve of first closure set trachea, open the unidirectional air outlet valve of exhaustor, the gas of first breathing out just can be discharged through exhaustor, when expiration proceeds to final stage, close the unidirectional air outlet valve of exhaustor, and open the unidirectional air outlet valve of discharge, in pulmonary gases (testing desired gas) the inflow gas collection bag of rear exhalation, thereby successfully get rid of the first breath of interference test result, guarantee the effective collection to test desired gas.
Accompanying drawing explanation
Fig. 1 provides the structural representation of breath test gas collector for this utility model;
In figure:
1. the unidirectional air outlet valve 3. exhaust gas recovery bag 4. Storage Time in Gas Collecting Bag 5. external screw thread bodys of blow gun 101. groove 2. blowning installation 201. air inlet pipe 202. discharge 203. exhaustor unidirectional air outlet valve 205. exhaustor of 204. discharge
The specific embodiment
In order to make those skilled in the art person understand better this utility model scheme, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the breath test gas collector that this utility model provides is made up of blow gun 1, blowning installation 2, Storage Time in Gas Collecting Bag 4 and an exhaust gas recovery bag 3.Wherein blowning installation 2 is " T " font by air inlet pipe 201, discharge 202 and exhaustor 203 and is intersected in a place and forms, on discharge 202 and exhaustor 203, be respectively equipped with the unidirectional air outlet valve 204 of discharge and the unidirectional air outlet valve 205 of exhaustor, make gas only may, from two bodys from flowing out, and cannot flow into body; The mouth of pipe of air inlet pipe 201 is connected with blow gun 1, the mouth of pipe of discharge 202 is connected by external screw thread body 5 with the upper end bag mouth of Storage Time in Gas Collecting Bag 4, the top of external screw thread body 5 can be plugged on the mouth of pipe of discharge 202, the bottom of external screw thread body 5 is provided with external screw thread, can be fastened together with the female thread of Storage Time in Gas Collecting Bag 4 bag mouth inner sides, prevent gas leakage.
As further improvement, connect an exhaust gas recovery bag 3 at the mouth of pipe of exhaustor 203, the design at its bag mouth place is identical with Storage Time in Gas Collecting Bag 4.
When use, the unidirectional air outlet valve 204 of closure set trachea, open the unidirectional air outlet valve 205 of exhaustor, patient is taking after isotope-labeled medicine, bite blow gun 1, start to exhale, while approaching last pulmonary expiration phase when exhaling, close the unidirectional air outlet valve 205 of exhaustor or clutch exhaust gas recovery bag 3 bag mouth that (two kinds of methods select one can seal exhaustor 203 mouths of pipe, if but that both carry out effect is better simultaneously), open the unidirectional air outlet valve 204 of discharge, pulmonary gases is successfully collected in Storage Time in Gas Collecting Bag 4.
